DX12 Is Able to Handle 600K Draw Calls, 600% Performance Increase Achieved on AMD GPU

[el etro]

What about Intel? How will DX12 affect (low power) laptops?

Will affect, most DX12 is centered on remove CPU bottlenecks, as far as we know...

You mean AMD who has literally spent *years* ahead of this on a similar low level API? If anything its reasonable to expect AMD to have better low level drivers out of the gate than Nvidia as long as we're going for baseless speculation. In a few years, who knows. I do trust Nvidia's driver team a bit more, but lets not pretend AMD doesn't have a head start here.

That doesn't even take into consideration that it's AMD hardware in both consoles and there is reason to believe that more time is going to be spent making AMD hardware work than Nvidia. If mantle has taught us anything, its that the work done by the game dev is going to have even a greater impact on how well the low level stuff works.

Nvidia seems to have no trouble with DX12. A much better implementation as DX12 from nvidia can already be seen in star swarm and I expect this to continue.

It's quite likely that a low level API is going to expose architecture differences more. You may see more wild swings in performance from one game to the next in comparison to the other brand.

Actually watching the videos shows nVidia is missing certain parts of the graphics on starswarm in dx 12 compared to AMD.

This was discussed in the other thread. Alatar provided a good post that shows comparisons between DX11 and Mantle, followed up by explanations from other posters. Higher framerates = more blur.

No, it's not blur that I am talking about.

You are talking about the colored trails, which are reduced/eliminated when blur takes over...

The evidence is in the graphs above, AMD does really badly under DX11 in starswarm, where as nvidia does much better. This because nvidia having no mantle optimised DX11 as best they could to make it work ok, where as AMD didn't bother relying on mantle. Unfortunately most games don't support mantle, and even when it does work it's often buggy. Having no mantle and a DX11 driver that performed like the nvidia one would have worked out better most of the time.



You optimse for whatever the industry are using broken or not as that's what users need to play the games. Most games right now use DX11 so we need the best DX11 drivers possible.

You are rationalizing. Then, instead of proposing it as a possibility, you pronounce it's the truth, the facts, the way it is. You have presented no evidence at all. AMD has Mantle, therefore they don't care about DX. Even though, as you later stated it's what most games use and needs to be supported.

The same guy that championed mantle? ()

Point?

No, seriously watch the videos.

The move to 20nm is still going to be bigger than the move to DX12.
